Is there a way to maximize the chrome browser window using python selenium WebDriver?

Note: I am using Chrome Driver 23.0 Any solution on this would be greatly appreciated!

You could use ChromeOptions and set suitable argument:

options = ChromeOptions()
options.add_argument("--start-maximized")
driver = ChromeDriver(options)

not working for me - the window snapshot show that the size is only 800x600

Janek Królikowski Over a year ago

@NamGVU check what's the actual screen resolution while executing test - the maximum size is the size of the resolution. I had this problem some time ago because of test being run by process executed as a service. This caused process to be run in Session 0, which has limited capabilities when it comes to screen resolution. Running tests not in a services solves that issue.

I run it on ubuntu server; so i guess the screen size set by Xvfb. Thanks to point it out.

This is 2017/12/15 now. driver.fullscreen_window() works.

driver.maximize_window() is more comfortable function that works with selenium chrome driver in python.

Nothing worked for me except:

driver.set_window_size(1024, 600)
driver.maximize_window()

I found this by inspecting selenium/webdriver/remote/webdriver.py. I've never found any useful documentation, but reading the code has been marginally effective.

This is a better answer than the other ones since this one supports all browsers and not just Chrome.

You don't actually need to set the window size first.

For me, maximize_window had no effect. Not doing set_window_size kept the window at 800x600, set_window_size(1920, 1080) before calling maximize_window and when not calling maximize_window made the window size 1920x1080. fullscreen_window caused my code to hang. I'm using Chrome with options.add_argument("--headless").

Based on what Janek answered, this worked for me (Linux):

from selenium import webdriver

options = webdriver.ChromeOptions()
options.add_argument("--start-maximized")

driver = webdriver.Chrome(chrome_options=options)

This didn't work for me on Linux at first, but updated the Chrome driver with sudo apt install chromium-chromedriver and it worked then.

Taher A. Ghaleb Over a year ago

webdriver.Chrome(options=options)

For MAC or Linux:

ChromeOptions chromeOptions = new ChromeOptions();
chromeOptions.addArguments("--kiosk");
driver = new ChromeDriver(chromeOptions);

For Windows:

ChromeOptions chromeOptions = new ChromeOptions();
chromeOptions.addArguments("--start-maximized");
driver = new ChromeDriver(chromeOptions);

Question is specifically for python.

--kiosk is only one that worked for me on Mac. Thanks.

hoefling Over a year ago

Keep in mind that once using --kiosk, trying to change window size will crash the driver, example (python):

opts = webdriver.ChromeOptions(); opts.add_argument('--kiosk'); driver = ChromeDriver(chrome_options=opts); driver.set_window_size(800, 600)

. Either fullscreen or windowed.

Try this:

driver.manage().window().maximize();

This works for me, with Mac OS Sierra using Python,

options = webdriver.ChromeOptions()
options.add_argument("--kiosk")
driver = webdriver.Chrome(chrome_options=options)

While this code may answer the question, providing additional context regarding how and/or why it solves the problem would improve the answer's long-term value.
